One additional notion about how it happens:
runtimeservice.suspendProcessInstanceById flush all changes into db, including ConcurrentExecution object. But then each async subprocess try to flush the same values.

Could you create a unit test and create a JIRA (with the unit test as attachment)?

Best regards,

I've wrote a simple demo (only a few dozens of lines) that illustrates my problem
git clone https://github.com/JOLO-/ActivitiOptimisticLockingException-during-suspension.git

P.S.
1. Seems I've no rights to create an issue.
2. Not sure that I've understood you properly when you ask me to write a unit test. Is my demo an unit test?

Do you check the demo below?

This is just how optimistic locking works… If another thread is running the service-task, and you suspend the process, either the suspend-action OR the commit of the "completed service-task" will get an exception and roll back. That's just the way it works
